FRANKLIN L. LANE, OF BELOIT, W'ISCONSIN'l ASSIGNOR TO P. B. YATES MACHINE WOODWORKING MACHINE.

Application filed January'12, 1925.

The` present invention relates to woodworking machines, and is particularly concerned with a machine for finishing railway ties. The invention, however, is susceptible of incorporation in machines for performing generally analogous operations upon work other than railway ties.

The principal object of the invention is to provide an automatic machine of the character described which is adapted to receive railway vties in a rough-eut state and deliver the same in a finished condition ready for thereception and attachment of the rails.

The machine hereinafter disclosed as illustrative of the invention will ent seats in the ties for therail plates or the rails. will here holes in the ties at the seats for the spikes, will cut the ties to length' with their ends equally spaced from the seats, and will mark the ends of the ties with any desired data. The machine will automatically perform all of such operations in proper synchronism, and will furthermore automatically discontinue certain of such operations under those conditions of operation in which a temporary interruption becomes necessary.

While the foregoing statements are indicative ofthe nature of the invention, many other ohjects and advantages will he. evident; to those skilled in the production of railway ties Upon an understanding of the construction, arrangement and operationof the machine which is disclosed in the accompanying drawings and in the following detailed de.- scription. The machine selected to exemplify the inventionis susceptible of heing modified in numerous respects Without departing from the spirit of the invention as defined h v the comprehensive scope of the appended claims. and a few of such modifications are disclosed in the drawings: and description as illustrative of this statement.

Reference will first loe made to that form of the invention illustrated in Figs. 1 to `19 inclusive of the drawings.

The several hereinafter described mechanisms of the machine whichembodythesalient features of the invention are mounted upon a generally rectangular frame 10. In the operation of the machine, the tics to be finished are moved sidewise in single order from the in-feeding end of the frame 1() to the out-feeding end ot the same, and are act fd upon hy the mechanisms in the course of such movement.

The adzing mechanism (see Fig. 2)- which operates to cut two spaced seats in a commonV plane in the tie for the reception of the usua 1ail platcs-includes two adjustably spaced cutter heads 11 which are secured to a horizontal transverse shaft 12. The shaft 12 is journalcd in the sides of the frame 10. and is rotated rapidly by an electric motor 13, at one end of the same. The heads 11 cut the seats in the under side of the tie wnile the tie is being moved thereabove along` two supporting rails 14 which are positioned along the sides ot the frame 10 in vertical planes closely adjacent the sides of the heads and at such elevation with respect to the heads as to cut the seats to the desired depth. The heads 11 are suitably encased at all points below the top level ot' the rails 14, and the shaft 12 is additionally supported intermediate the sides of the frame 10 in a journal on a longitudinal trame member 15.

The sawing mechanism (see Fig. 2)- which operates to cut the ends ot the tie at points equidistant from the seats cut hy the adzing mechanism-includes two spaced disc saws 16 which are secured to the shaft 12 exteriorly of the heads 11 and the rails 14. The saws 16 project segmentally above the rails 14 a distance well in excess of the thickness ot the tie, and cut the ends of the tie squarely while the heads 11 are cutting the seats.

The conveying mechanisn'l (see Fig. 2)- which operates in three stages to move the ties sidewise in single order through the machine-consists of an intermittently operating device 17 at the iii-feeding end of the frame 10, a continuously operating device 18 to which the tios are transferred from the device 17, and another interlnittently operating device 19 to which the ties are transferred from the device 18.

The feeding device 17 of the conveying mechanism (see Figs. 1 and 5)-includes two reciprocating hooks 20 which are positioned in transverse alignment alongside the rails 14 at the in-feeding end of the machine. The hooks 2O move away from the iii-feeding end in raised positions above the top level of the rails 14` and return toward the iii-feeding end in lowered positions, whereby to draw a tie placed upon the rails 14 into the machine along the rails and then return and repeat the operation on the next tie. The alter nately raised and lowered positions of the hooks 2O is effected by supporting the hooks on rollers 21, which rollers travel, in their advance movement, on raised tracks 22 until at the end of such movement they reach the ends of the tracks and drop down, and in their return movement, on lowered tracks 23 until at the end of such movement they pass through inclined one-way doors 24 into position to ride up the doors onto the raised tracks 22 upon their next advance movement. The reciprocating movement of the hooks 20 is effected bv coupling the advance ends 25 of the hooks to the upper ends of levers 26 which are oscillated from a shaft 27 through connecting rods 28 and crank arms 29. The shaft 27 of course, makes one revolution to each feeding movement of the hooks 20.

The feeding device 18 of the conveying mechanism (see Figs. 2 and 3) consists of a number of sharply pointed dogs 3() which are carried in transversely aligned pairs by two endless chains 31. The chains 31 are trained at one end of their travel over idler sprockets 32 and at the other' end of their travel over drive sprockets 33. The drive sprockets arel secured to a shaft 34 which is rotated from a shaft 35 through a number of intermeshed reduction gears 36 (see Figs. 6 and 7). The upper stretches of the chains 31 may be supported in channel members 37 to prevent the dogs 30 from tilting back out of their normal positions under the resistance otl'ered by the ties when being advanced by the dogs. The dogs 30 move up behind a tie which has been left by the hooks 2O in position for the dogs, bite into the rear side of he tie, and advance the tie slowly along the rails 14 through the zone oi action of the adzing and sawing mechanisms.

'.`he feeding device 19 ot the conveying mechanism (seo Figs. 2 and 3) consists ot two lugs 38 which are carried in tiansvers:` alignment by two endless chains 39. The chains 39 are trained over idler sprockets 40 at end of their travel and over drive sprockets 41 at the other end of their travel. The idler sprockets 40 are journaled freelyv on the shaft 34 at. the sides of the sprocli .ts 33, and the drive sprockets 41 are secured to a shaft. 42 which is rotated from the shaft 35 by a chain and sprocket connection The lugs 33 move. up behind a tie which has been Vleft by the dogs 30 in posi ion tor the lugs, and advance the tie along two ,'iupporting rails 44 ont o rollers 45 carried by the rails 44 beyond the device 19 and directly over the boring mechanism hereinafter describe-d. The rails 44, which serve as continuations ot' the rails 14, are positioned in longitudinal alignment with the centers of the cutter heads 11, and the seats cut in the ties by the heads accordingly bear upon the rails 44 and support the ties with the seats thereof in a true horizontal plane for accurate work by the boring mechanism.

ing` movement oi the tie hy the device il) relatively rapid and corresponds to that ot the device 17, as the device 19 must etiect a cycle of operation while the device l n is moving only the distance between two successive pairs of dogs 80. The means ter rotating the shaft 27 ot the device 17 consists ot and sprocket connection f en 27 and the shaft Prlot' the means for rotating the ,sha i rotates the shafts Si and fifi? and 19, consist of a large gia the shaft 35, a relativelyv sn cured to a shaft 119 and meshcd wlh 47, a large gear secured to the s, relatively small pinion 5' j'oiu'nalz'f.

The boring mechanism Figs. 9, l0, 11 and `12)which operates to drill a numl'ier of holes through the tie within the areas ot the seats forthe reception ol' the spiles-includes two drill units which are mounted for vertical movement in two guiding frames 56 positioned below the ends of the rails iii. Each ot the drill units consists of tour drills F7 removably mounted in rotatable holders 58, an electric motor 5!) having au armature sha tt 60, and an enlarged pinion (1l on the armature shaft meshing with gears on the holders 58. The guiding iframes 5o are adiustahly spaced from each other at points equidistant from the center line ot' the inachine loy means oi an axiallyv non-movalle rod 63 having oppositely directed screwthread connections 64 with the trames 56 and an adjusting hand wheel 65 at one extremity. When it is desired to change the dista nre hetween the drill units to correspond to any change made in the distance between the cutter heads 11, the hand wheel (S5 is turned and the guiding frames 56 containing the drill units 55 are as a consequence shifted.

The drill units 55 move upwardly when a tie is placed therealoove by the lugs 38 of the feeding device 19, and the rotating drills 57 here the holes in the tie during such upward movement. The means li'or moving the drill units 55 upwardly consists ot two vertical racks 66 secured to the units. two pinions (37 secured to a shaft 68 and rneshed with the racks lill clutch element 69 Jiournaled 'Freely on the uhait 68 and rotated continuouslyY from the shaft lof.' intermeshed gears 7() and 71 secured respectively to the shaft 35 and to the clutch element 59, and another clutch element 78 splined to the shaft ($8 and shifted axially thereof under action ot a compressed spring 73 into engagement with the clutch element 69. The eoacting faces of the clutch elements may he provided with interiitting lugs and sockets 71 ior etliecting the desired driving connection hetween the elermnts. dien the driving connection etieeted, the shaft 68 will he rotated from the shai't and will cause the drill units to move upwardly. Vr'hen the units reach their uppermost positions and have accordingly con-ipleted their horing operation. :i deilector plate 75 on the periphfe-l'g. of the conrinuourdjY rotating clutch element (59 revolve s into cai'nming engagement with a relier 7G on a pivoted lever 77 which is journaled intermed'ate its ends on a collar 78 of the clutch eleiV- ui 72, and forces the clutch ele; ent i2 axially away from the clutch element 6i) to release the driving engagement therebetween. 'ihe dis ngagement. oi the clutch element "322 from the shaft G8 permits nuits to drop to their lowermost position in readiness for the nent drilling operation. 1n order to insure that the drills will not catch accidentaliy in the ties and thereby prevent the drill units from dropping, an arm 79 is secured on the shaft 68 in such position relative thereto that. when the drill units are ready to drop, the arm will assume the horizonte 1iosition shown in Fig. in the path ot a vertically n'iovahle, roller 8l). The roller is mounted on the free end of a pivoted lever 8i which is, oscillated in a vertical plane hy means oi a lint: 82 which is pivoted eeeentricallj.' to the collar on the end oi' the shatt 35. li' the, drill units should not drop immeiliately upon the eonig'aletion of' the boring operatimfi.r the roller 8O will push the arm 7l) upwardly and start the reverse rotation of the shaft (38 which u'iusl olz-viousig' accompany the dropping action of the drill units. The drill units are prevented trom dropping too rapidly hg; a zoning-pressed lzrale shoe 853 which hears agili. rst a Vrictiou drum 84 on the shaft o8 and acts 1.o moderate the reverse rotation ot the same.

The positioning mechanism (see Figs. 1, 2, 23, 9 and 1)`which operates to hold the tie in a centered position above the boring mechanism during the horing operationinchicles two spaced cruei'l'orm spiders which are secured to a horizontal transverse shat't 86 positioned directly above the boring i'ueehanism.
